hi all,i was chatting with a owner of a new powerjoke at the fuel station the other day,he told me his truck has a multi stage turbo with 2 diferent sized veins,the way he described it,it sounds like a factory set of twins,he claims no lag at all,is he right and will one fit on our trucks?not that i want a ferd part on my truck but if its like twins i will search for one at the wreckers.thanx

 

there are spossed to be a few new test powerstokes out there with the new 6.4 twin turbo in them so it could have been a set of factory twins .

 

Found this on the net, looks like fords will have some good power making capabilities...air-wise at least..


6.4

The 6.4 L Power Stroke, due out for the 2007 model year Ford Super Duty trucks are redesigned, will have twin sequential turbos — a smaller one feeding the bigger one. The benefits of this are faster spool-up times, smoother power delivery, and better fuel economy and emissions. The 6.4 L will probably be based on the 6.0 L block but may be a Ford design.

The engine is said to produce 350 hp (260 kW) and 650 ft·lbf (880 N·m). [1]

 

This is new technology and people are trying to get this to work on our trucks. Look at the aurora MST from ATS. So what if he has a nice turbo on a junk motor =P

 

Aww, c'mon now. They perform great and flawlessly when used properly as a boat anchor !

 

The present crop of 6L fords use a "variable geometry" turbocharger , he has the right idea , but he explained it wrong , there are veins in the exhaust housing that guide the exhaust as it comes in , making it hit different parts of the turbine wheel, it starts at the outside edge , to decrease spool up time , and as the turbo spools , it directs the air closer to the center of the turbine , making it spin faster , and producing more boost.

I would not be too excited about fords new twin setup , it is an international based engine, and international has been using a 6 cylinder verson for a while it in's small cab over trucks, it has alot of power (stock for stock, it probably woulda taken my cummins off the line , even considering the one i drove had a 20' van body on it) but on the highway it falls flat on it's face. Anyways , to my point , i have already seen a few turbocharger failures (and one runaway, that we think got to around 8000 rpm before the internal engine components vaporized).
